Description: Instance migration in cloud computing refers to the process of moving a virtual machine instance from one host to another within a cloud environment. This process is fundamental for the efficient management of resources in data centers, as it allows for load balancing, optimizes resource usage, and ensures service availability. Migration can be hot, where the instance continues to run during the transfer, or cold, where the instance is stopped before being moved. This mechanism not only improves operational efficiency but also contributes to system resilience, allowing maintenance on physical servers without interrupting service. Additionally, instance migration facilitates disaster recovery by enabling workloads to be moved to other hosts in case of failures or technical issues. This functionality integrates with other resource management features, providing administrators with tools to effectively monitor and control the cloud environment.
